POULTRY BRGODER.

Application filed October 25, 1921, Serial No. 510,253. Renewed September k20, 1922.l Serial No. 589,485.

To all 'whom t may concern Be it known that I, CHARLES U. VINBERG, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented a new and useful Poultry Broeder, of which the following is a specification.

This invention relates to poultry broeders.

The object is to provide a device for use in connection with incubator hatched chicks whereby the latter may nd ample space to hover beneath the roof of the brooder and within. the confines of sheltering curtains surrounding the margin thereof, and to be subjected to a uniform v degree of heat throughout the entire area, thus avoiding the usual crowding and constant movement of the individual chicks in an effort to gain positions nearest to the heating means found in the ordinary devices of this class.

Another object is to provide an electrically heated brooder having means for freely admitting the heat from resistance coils to reach to the floor or other support for the chicks, and at the same time prevent their coming into contact with the same by means of a screen arranged over their heads a suitable distance to permit their free movement within the confines of the broeder.

A further object is to provide a brooder having means for admitting the chicks at any point around the periphery thereof or permitting them to leave the same in like manner, the walls of the broeder immediately closingagain thereafter to exclude the cold atmosphere and maintain a uniform temperature within, the device being suspended from above to permit of such action of the chicks.

A still further object is to provide ventilating means for the interior of the brooder whereby the same may be supplied with fresh air caused `by a constant' upward flow of heated air through the ventilator, resulting in a gentle inflow of fresh air from beneaththe bottom of the conning or shel tering curtains and between the crevices therein, thus avoiding subjecting the chicks to any violent drafts of air which often provedisastrous.

A. full and complete understanding of the invention may be obtained from a consideration of the following detailed description taken in connection with the accompanying drawings forming a part of this specification; it being understood that while the drawings show a practical form of the in vention, the latter is not to be confined to strict conformity therewith, but may bev lar reference characters designate corresponding parts throughout the several figures:

Figure 1 is a side elevation of the improved brooder.

Figure 2 is a vertical, diametrical section of the same, taken on the line 2-2 of Figure 1.

Figure 3 is an inverted plan view of the broeder. Y

rfhe broeder comprises a pyramidal hood or cover l, circular in plan view, and made of a sheet of suitable metal having` its center formed linto an apex considerably higher than the marginal edges thereof, and its joined edges. (not shown) may be overlapped and riveted or soldered together or crimped in a well-known manner.

The hood or cover l is provided with an l integral, marginal flange 2 depending` from its outer circular edge and entirely around the same, the metal comprisingthe flange being returned upon itself at the. bottom thereof to form a strengthening and stiening rib 3 at the base of the flange, and in spacedL relation to the floor or other support 4t for the chicks, when the hood or cover is v the hood or cover l, ata point adjacent tol the upper edge of the dependingl flange 2, are bent to provide a substantially horizontal step-like ring 7 which not only strengthens the cover and acts to prevent denting the saine, but proviiles a convenient place iforthe attachment et a serios et insulators or posts S, located beneath the cover and held to the same by means of bolts having;` their heads preterably located on the upper or outside el the cover.

Conductors 10 coming frein an),Y suitable source of electrical energy are appropriately connected to a multi-peint snap switch 11 niounted upon the upper side of the cover or heed 1 and over an opening 1Q, as shown in .Figure- 3 el the drawing, 'through which other conductors 13 lead in opposite directions to a pair oi the insulating posts 8. rlhe terminals et the wires areihere connected to resistance wires, preferably iornied into coils 14e, which are passed back and forth between and attached te the insulating; posts 8 in any desired manner se as to cover the area within the enclosure,and the other terminals et said resistance wiresare connected to a pair of the insulating pests 8 diametrically opposite to the inlet loit the cenductors 13, where they are joined by a transversely disposed resistance coil 15.

- Leadingv from the pests 8 having` the inlet ends of the resistance coils attached thereto, are other conductors 1o also in electrical .connection with the feeders 18, and provided with the usual insulating covering' and ing' around in 'the interior et the 'flange Q et the hood and substantially on level with the stillening1 rib 3 to a point diametrically opposite to the inlet 12, where 'they pass through an opening 1T and having their t niinals connected an ordinary lanip soelierv 18, attached to the cover on the outside thereoi2 and adapted to have an ordinary electric lamp 19 screwed into the sanie, to enable the operator to knew at a glance when the current is turned on by the switch 11' and the heating of the broeder is in progress.

A circular screen 2O :termed et sonic suitable wire mesh, having` its margin bound to a stiii' wire ring 21 of a di arneter to freely enter within the depending flange f2, adapted to be placed therein and to be held in position by Flexible nietal clips Q2, soldered or otherwise secured .to the return bend P, el the flange Q and at spaced 'intervals around the saine, the said screen conlininp; the resistance coils 1i and preventinrY the chicks lroni eenling` in contact with 'the saine.

A. band of seine sett tl blc wovon fabric, such :is double-'taced extra lie/avv canton, 'tlanneh is tted tightly irouiul the depending danse, its upper edge abutting against the bead 2 rined between the bodyT oit the hood or cover and the said depending flange, and projecting below the return hond 3 sutliciently to nearly touch the floor or ground ./l, the said lower projecting?,- portion being; provided with spaced slits 24- to facilitate theentrancc et the chicks into the interior of the broeder. l

A 'voutilating?,- tube 25 formed el' suitable metal, has its upper end soldered or otherwise secured to the interior oit the apex oilE the h ood or cover 1, which is provided, within the confines of said tube, with a series el? pe 'z'orations .26 for the outlet et warmed, rising air passing through the tube 25 from below the screen 20, the lower end of the ventilator being` provided with the flaring inouth 27 resting` directly upon the screen 20. n

ldlhen the switch is turned on the resistance coils becenie heated and heat the air throughout the broeder, the chicks being prevented from becoming burned thereby by reason oit the screen, and during,i the time 'the electric current is turned and the heating` process progressing the lamp 19, which is preferably of low wattage', is glowing and constitutes a signal to the operator that the device is in proper operation.V

lEroni the t'oregoing' it will be seen that simple and economical broeder has been provided which may be operated at a low cost, and by reason of its simple construction, niay be cheaply manufactured and sold cheaply, that the chicks may liever within the saine and encounter an even ytemperature without any danger of becoming burned by comino' in Contact with the heating elements. y

llllhat is claimed is il, fr poultry broeder comprising an inverted sheet-metal. heed provided with a depending marginal flange, a band oi? fabric stretched around the flange and extending` below the same and having` its lower extending portion slitted te provide curtains, nieans :tor suspending the hood, insulators mounted within the hood, resistance coils reaching' freni insulator to insulator te cover the area within the hood above the lower edge of the flange, electric conductors en` laine icing' located on the outside et the hood, clips carried by the Hangs to support the conductors, and a circularscreen also supported by the clips above the bottoms olf' the curtains. v y

2. il poultry broeder coniprisinc,r an iufvcrtcd shect-niez'gal hood provided, with a deprixding marginal damn, a band olli fabric stretched around the flange and ontendinaq below the saine and having1 its lower extending portion sl ted to provide curtains, :means for suspez izhe hood, -insulators mounted withiuthe hood, resistance coils reaching trein insulator te insulator to cover the area within the hood above the lower edge el" the flange, electric conductorsenterinthe hoed and connecting with the coils and having' a switch anda glow lamp included in the circuit, said switch' and 1511111111 being located on the outside of the hood, clips married hy the ange to support the conductors, L oreulal' screen having zt marginal ring also supported by the Clips above the bottoms of the Curtains, and :L ventilator tube extending' to the Screen and secured to 'he apex of the hoochA the latter having perfolatol'ls to provide an outlet 'for as my own, have hereto afxed my signature. l
